Getting unfolded SphereGeometry 2D plane

Hi guys,

Im working on a tile system in order to split a big image texture into small tiles. As a improve i need to request the visible tiles only.

My first question is how can I get the 3D SphereGeometry converted to a regular 2D geometry?
And how can I convert camera looking to a small 2D geometry within the above 2D geometry?

Any support is appreciated

This part sounds like a 2D problem.

Are you thinking of a mapping application, like Google Maps(2D), Google Earth(3D)?
Please provide more info.

Do you mean something like this?

See the respective examples from the Collection of examples from


Images splitting is not actually an issue for me. I am stuck on creating a 2D representation of the 3D SphereGeometry

How about using UV coordinates for the 2D representation.

For starters, I’d suggest you start with reading this article on map projections, so we use the same established terminology.

Then you’ll need to decide, if you’ll want to cover the whole spherical surface in your application, or merely a small patch of it.
